Experiencing frequent computer self-restarts or unexpected shutdowns during your tasks or gaming sessions without any prior warning? Fret not, follow this article to uncover the reasons and remedies for the automatic restart issue!
1. Malfunctioning Hard Drive
If your computer's hard drive is malfunctioning, and your work files reside in the affected area, you might encounter a scenario where the computer restarts continuously.
Troubleshooting:
Method 1: Press the Windows + E key combination, right-click on drive C > Select Properties.

Right-click on drive C
Select the Tools tab > Click on the Check option to examine the hard drive for errors.

Choose the Tools tab, click on the Check option
Method 2: Utilize software tools for hard drive diagnostics, such as CrystalDiskInfo or Repair Disk Manager.
If a faulty hard drive is detected, users should transfer crucial data to another drive before replacing the problematic hard drive.
2. Excessive Machine Temperature
Continuous operation of the computer for an extended period can lead to overheating, causing automatic resets or shutdowns to safeguard the system and processor.
Troubleshooting:
+ Disassemble the computer and clean its components to prevent the accumulation of dust over time.
+ Replace the thermal paste for the CPU.
+ Add additional cooling fans to the computer during operation.
+ Position the computer in a well-ventilated, cool area, away from heat sources, to maintain a stable temperature.

Operating continuously for an extended duration
3. Weak or Unstable Power Supply
A crucial factor ensuring stable device operation is the power supply unit. If your computer is experiencing continuous restarts without displaying anything on the screen, it might be due to a weak power supply or the addition of external peripherals such as speakers, external HDDs, etc., causing a drop in power.
Troubleshooting: Use a power supply with higher voltage than the old one, consider adding a small power stabilizer or an Uninterruptible Power Supply (UPS).

4. Caused by Viruses
Many users often encounter the issue of continuous computer restarts due to viruses infecting the computer or software, harboring malicious code that severely impacts the system's operation.
Troubleshooting: Use antivirus software to address this issue and ensure device security. If the problem persists after installing antivirus software, consider reinstalling the operating system to thoroughly resolve this issue.

Using antivirus software is recommended
5. Graphics Card Issue
The computer's graphics card may experience malfunctions due to excessive application usage, causing the device to overload and restart continuously. In such cases, it's advisable to close unnecessary applications and remove the graphics card for component cleaning.
Troubleshooting: Close unnecessary applications and remove the graphics card for component cleaning. Thoroughly inspect before reassembling the components.

6. RAM Issues
The computer's graphics card may experience malfunctions due to excessive application usage, causing the device to overload and restart continuously. In such cases, it's advisable to close unnecessary applications and remove the graphics card for component cleaning.
Troubleshooting: Disassemble the computer to access the RAM module, clean the RAM pins (copper pins) and RAM slot thoroughly, along with the surrounding components.

7. Depleted CMOS Battery
Another cause leading to continuous computer restarts is the depletion of the CMOS battery. Remove the CMOS battery from the computer, wipe it dry and clean, and test it with an electrical pen to check if it still holds a charge.
Troubleshooting: If there's no charge left, it's time to replace the battery. On the contrary, if the battery is still functioning well, clean and scrape off any rust at the contact points between the CMOS battery and the mainboard to improve the connection.

8. Due to Faulty Battery
After prolonged use, a laptop battery may deteriorate, commonly referred to as 'swelling,' causing the battery to function less efficiently or, in some cases, not at all without direct connection to a power source, like a desktop computer.
Troubleshooting: If facing computer restarts due to a faulty battery, simply replacing the battery will restore normal functionality.

Simply replace the battery to resume usage
